The invention relates to new and useful improvements in metalcontainers, and more particularly to a metal container of the r1p striptype provided with an inserted collar with which a cover makes slipengagement for re-closing. y i r i object of the invention is to providea collar fora container of the above type made from a strip of metalhaving the ends thereof locked together byfthe' inter-engaging andfolding of metal parts disposed relative to each other, so'that theouter face of the collar is of uniform diameter and makes intimatecontact with'the inner face of the body wall of the container throughoutthe entire cir cumference of the collar.

.In the drawing i Figurel is a sectional view'through a container withthe improved collar inserted therein; L

"Fig.2 is a sectional view on the line 22 of Fig. 1,'and-' f .Fig. 31isa view showing the ends of the collar detached andwith the holding lugspositioned at right angles to the face of the collar, 'andalso showingthe depressions in the inner lap which are formed when the lugsfareturned down and pressure'applied thereto. g

The invention is directed to a metal container which includes a bodyportion having the ends oined thereto preferably by double seaming. Thebody wall adjacent one of the double seams is provided with score linessetting off a rip strip to which a key may be of the strip overlap eachother. The inner lapping end is provided with an elongated open ngextending lengthwise of the strip; The other'end of the strip isprovided with lugs which are cut from the strip and-bent so as to extendat right angles thereto. These lugs are so positioned that they passthrough said elongated opening, afterwhich the lugs are folded downagainst the inner face of the strip. After the lugshave been foldeddown, pressure is applied and this will cause the lugs to formdepressions in the inner lapped section, forcing the depressions intothe openings in the outer lapped section formed by striking up the lugs.The end of the inner lapping portion is offset from the body of thestrip so that the'outer face of the strip is of uniformdiameterfthroughout, and

willmake intimate frictional contact with the inner face of the wall ofthe container body. I

Referring more in detail to the drawing, themetal' container as shownincludes a'body portion 1 which isprefera'bly cylindrical in shape. Onlyone of theends is shown. This end is indicated at 2 and it is secured tothe body portion 1 by a double seam 3. The wall of thecontainer body isprovided with a score line 4 and also a score line 5. These score lines4.- and5 setoff a ripping strip 6to which a key may be applied fortearing away the ripping strip and thus releasing the end or cover 2from the container body. Inserted within the container prior to theapplying of the end thereto, is a'collar 7 The collar together. The endf the collar is the outer lapping portion. This end is provided withlugs 9 and 10 which are struck up from the metal in th'e'collar, and areinitially formed so collar.

7 has the ends thereof lapped and secured f 11 is formed, and by thestriking up of the lug 10,'an opening 12 is formed. a

The end 13 of the collar band is the inner lapping end. This end13either prior to the r oiningv of the ends, or during the joining of 1a construction so that when the two ends are joined, the outer face ofthe collar adjacent the line 14 on one end of the collar, will be flushwith the outer face of the other end of the collar. This produces acollar, which as clearly shown in Fig, 2, is of uniform diameterthroughout, and therefore, the outer face of the collar will makeintimate contact with the bodywa'll 1 of the container, as shown in thisfigure. The end 13 of the collar is provided with an opening 16therethrough adapted to receive the lugs 9 and 10. After the lugs havebeen inserted in this opening, theyare folded down on to the inner faceof the endsection118, andpressure applied. The pressure will cause themetal at the ends of the opening 16 to be depressed or forced into theopenings; 11 and 12 as indicated at 15,15. This not only aids in the:locking of the two ends together, but it also produces a CI1Si3I'1lC1contents of the container.

tion wherein the lugs are substantially flush with the inner face of thelapping section 13. The upper edge of the section 13 is inclinedasindicated at 17 so" as to avoid any sharp inner corner at the upperedge portion of the collar,-

From the above it will be apparent. that I hav'eprovided a collar .forinsertion in-a container body which is formed from a strip of metalhaving the ends thereof firmly locked together by an interlocking andfolding of the metal parts ofthe collar. These parts are so disposedthat the outer face of the collar is substantially of uniform diameterthroughout so that when it is placed within the container body, it willmake intimate contact with the inner wall of the container bodysubstantially throughout the entire circumference of the collar. Afterthe container is opened, the material in the container is passed throughthecollar in the dispersing of the If the content is of a liquid type,then it is quite essential that the collar shall make a liquid-tightjoint or connection with the body wall throughoutthe entirecircumference of the collar. Otherwise, the liquid will pass under thecollar and will run down the outer wall of the container instead ofthrough the collar and discharge from the outer lip edge of the collar.No matter whether the liquid content is poured from the container overthe connection betweenthe ends ofthe collar or at any other place, thereis no chance for escape of the liquid beneath the collar, for the reasonthat the collar, when the ends are joined, as'described above, makes anintimate liquid-tight contact with the container wall throughout theentire region where the ends are joined.

fore, the collar may be made so that it will have a tight frictionalgrip with the body wall when inserted therein, andcan, at the same time,be rounded into form and forced into thistight gripping contact with thewall of the container.

The score lines 4 and 5 are so disposed in I the present embodiment ofthe invention, that when the rip strip is removed,th'ere will beatportion 18 of the body wall left-attached to V the end 2 which projectsdownwardly so as to make an outside slip engagement with the collar 7for re-closure purposes. While I have shown the collar as used inconnection with a container having an outside slip portion formed fromthe bodywall, it will bev understood that this depending portionremaining attached to'the end. and forming therewith a cover, may beotherwise formed. Likewise, the collar instead of being substantially ofuniform diameter throughout and without any, rolled edge, may beotherwise shaped. The essential features of the invention reside in thejoining of the ends of the collar so that the outer surface of thecollar is of substantially uniform diameter through as to overlie therip strip, one end of said.

collar having an offset portion overlying the other end of the collar,one end of said collar having an opening: therethrough and the other endof said collar having a lug struck up from the metal'forming an openingadjacent the lug, said lug extending through the opening in the otherend of the collar and folded down against the face of the end of thecollar and depressing a portion of said end into the opening formed bystriking up the lug.
